According to US Weekly, shortly after ringing in the New Year, Swift and Styles went on vacation to the British Virgin Islands. And what was supposed to be a romantic island getaway ended in a nasty argument.

A source close to the couple said, “They had a fight [and] Styles said something he shouldn’t have… [Needless to say] this [breakup] is definitely going to be for good.”

While we can’t be certain what happened or what Harry said to Taylor, apparently, it was enough to cause her to put an abrupt end to their two-month whirlwind love affair. After the argument, she cut the vacation short and jetted back to her home in Nashville to lick her wounds and rehearse for an upcoming tour.

Meanwhile, Styles remained in the British Virgin Islands to finish out his vacation and try to make sense of it all. A source close to the pop star said, “Harry’s really upset about the split and is really sensitive about it,” adding, “he feels a little foolish now that it’s fallen apart so quickly.”

Swift is known for writing songs about her ex-boyfriends, which means she’s probably already working on one about Styles. So maybe we’ll find out what the argument was about after all.
